Lesson Summary
The method of creating division stories has five steps, to be followed in order:
Step 1: Decide on an interpretation (measurement or partitive). Today we used only measurement division.
Step 2: Draw a model .
Step 3: Find the answer.
Step 4: Choose a unit.
Step 5: Set up a situation. This means writing a story problem that is interesting, realistic, short, and clear and that
has all the information necessary to solve it. It may take you several attempts before you find a story that works
well with the given dividend and divisor.
